Please state what model year & engine size you have.
Sounds like you got one of those resistor things off ebay,
which is not a "performance chip".
Get rid of it.
The only thing the resistor does is amplifys the signal from your maf sensor
making it think more air is coming in, causing it to send more fuel.
Get rid of it.
Go to AutoZone & have them read the computer
for the codes that are causing the check engine light.
Did I mention,
Get rid of that resistor thing!
